Colossal Titan Build Calculator — UPDATE 4 launch math
Patched 2026-04-25 · UPDATE 4 launched today · numbers from patch notes, not yet field-tested
TL;DR — UPDATE 4 added the Colossal Serum with three skills (Seismic Shock 1000%, Tectonic Quake 800% + 400% AoE, Volley around 650% with flaming debris). Pair with the Arlert family for the AoE buff. The interactive calculator below translates skill × family × serum into per-cast damage and a rough Colossal Raid clear time.
The Colossal Titan is the headline of UPDATE 4 — the first new shifter the game's gotten in over a year. The kit is unusual: instead of one big steady-DPS form, you get three skills with very different shapes. Single-target Seismic Shock for boss bursts. Tectonic Quake with its path-AoE pulse for crowded rooms. Volley as a long-cooldown sustained damage option. Plus you can literally walk over smaller Titans to one-shot them, which is what most of the launch-day TikToks were about.
The numbers below are derived from the patch notes (Fandom's UPDATE 4 page plus the official trailer breakdown), not yet from my own runs — I'm writing this within a few hours of the launch. Field calibration will repatch the constants in 48 hours once I've done a couple of Colossal Raid attempts. If you're reading this on April 26 or 27, the numbers should be tighter.
Colossal kit — single skill read
Skill × family × serum tier. Output reflects one cast, the AoE bonus where applicable, and a full three-skill rotation DPS plus rough Colossal Raid clear time.
Output (approximate, ±10% — Day-0 estimates)
Full three-skill rotation deals about 37.89M damage across 35s of cooldowns — that's a sustained DPS of around 1.08M/s against the Colossal Raid's estimated 50M HP.
⚠ Arlert's headline buff is AoE damage — it doesn't boost Seismic Shock's single-target hit. Switch to Tectonic Quake to see the AoE multiplier in action.
What UPDATE 4 actually changed
The Colossal addition is the headline, but the rest of UPDATE 4 also touches your build. The Regiment system got a complete revamp (the developer comment said something like 659 messages in the bug reports queue, which lines up with how broken regiments felt pre-patch). New artifacts dropped — Warrior's Armband is the one most people will gun for first because it stacks well with shifter builds. There's a Waves rogue-like gamemode that gives a new currency called Shards (which the community is already confusing with the older Attack Shards from Update 1 — they're different things, see the UPDATE 4 serum tier list for context).
For Colossal specifically, the shifter form unlocks via the Colossal Serum, which drops from the new Colossal Raid. Drop rate scales with raid difficulty. As of writing this on launch day, drop rates feel tight — the patch-note language says "rare," which in this game usually means around 5-8% on highest difficulty. I'll patch in real numbers once I've done 20+ runs.
Family pairing — Arlert is the obvious pick (with caveats)
The patch notes are unusually direct about this: "Arlert is all about area effect Titan power. With boosts to Colossal Titan AoE, core titan stats, and crit chance, it's a solid pick for dealing with waves or crowded battles." That's as close to a developer endorsement as you get in Roblox patch notes.
But — and this matters for the calculator above — Arlert's buff is specifically AoE-flavored. If you're a single-target spammer who never touches Tectonic Quake or Volley, Arlert's multiplier doesn't apply to your Seismic Shock casts. In that narrow case, Yeager's flat Titan-stat buff actually edges out Arlert by a few percent. Most Colossal players will run the full kit, so most Colossal players will pick Arlert. But if you're a min-maxer with a clear-cut role in your party (boss-burst specialist), Yeager is a defensible alternate.
Skill rotation — front-load Seismic, then sweep
The clean opener is Seismic Shock first, then Tectonic Quake, then Volley. Total cycle is around 35 seconds of cooldowns and that's when you maximize damage uptime. The numbers in the calculator above assume you hit this rotation cleanly with no wasted casts.
On the Colossal Raid specifically, the boss has a large hitbox, so Tectonic Quake's path-AoE actually applies bonus damage frames against the boss itself — that's where the AoE multiplier stops being "just for waves" and becomes a real boss-DPS lever. This is a piece of the mechanic I want to confirm in actual runs (it's plausible but not guaranteed from patch-note language alone).
How I derived these numbers
Skill multipliers come straight from the UPDATE 4 patch notes (Fandom's page, plus the official trailer narration). Family multipliers are reverse-engineered from the previous Update 3 leaderboards — Arlert's AoE bonus is roughly 1.30x in observed AoE damage frames, Yeager's flat buff is around 1.05x on baseline Titan stats. Serum base damages come from my pre-launch grind (see /serum-tier-update-4 for the tier-by-tier reads).
Colossal Raid HP is approximate — the patch notes don't specify exact HP, but community datamines from the trailer footage put it somewhere around 50M with scaling per difficulty. That's the placeholder I'm using until someone publishes a confirmed number.
FAQ
How do I unlock the Colossal Titan?
The Colossal Serum drops from the Colossal Raid added in UPDATE 4, plus from the Emperor's Trove and Raiders' Chest end-of-raid drops. You need to deal 5% damage during the raid to qualify for a chest. Higher difficulty = better drop rate.
Which family is best for Colossal?
Arlert for full-kit play (AoE bonus + movement speed). Yeager if you're a single-target Seismic spammer. Marley/Warhammer is fine if you already mained that family pre-patch.
What's the rotation?
Seismic Shock (8s cd) → Tectonic Quake (12s cd) → Volley (15s cd). About 35 seconds for a full cycle. Weave basic attacks during cooldown gaps.
Is Colossal good against the Colossal Raid boss?
Yes — it's a raw DPS check more than a counter pick. The boss has a big hitbox, so Tectonic Quake's path AoE actually applies to the boss in some attack frames, which is a real lever if you confirm it on your runs.
Honesty clause
I'm writing this within hours of the UPDATE 4 launch. Numbers above are from patch notes plus reverse-engineered family multipliers — not from my own Colossal Raid runs. I'll repatch everything once I've done 10+ raid attempts and have field reads. If something here disagrees with what you're seeing in-game, trust the game — I'll catch up in 48 hours.
